Fig. 22 represents a front elevation showing theconnection from the rock-shaft O to the cam disk on the rotarydrivingshaft.

Similar lettersrefer tosimilar parts wherever they occur on thedifferent parts of the drawings.

A represents the frame or head of a wire nailin g machine in bearings,in which is j ournaled the driving-shaft a, which is intermittentlyrotated by belt power communicated to the loosely-rotatingfriction-pulley B, said pulley causing the driving-shaft to be rotatedone complete rotation and then causing it to stop for every time theshoe is pressed upward against the nipple shield or projection G on theforward end of the pivoted lever 0, (shown in Fig. 1,) as is common inautomatic starting and stopping mechanism for machinery of this kind. 1

I wish to state that I do not claim'as my in- .vention, any particularautomatic starting and stopping mechanism, and it is therefore notnecessary to describe such in detail, it being'sufflcient to state thatthe machine is started by pressing the work upward against the part 0 onthe forward end of the lever O,

by which the drivingrshaft is causedto make one complete revolution, cutoff a nail from the continuous wire, drive a nail into the work, andthen come torestuntil the work is again pressed upward against theforward end of the lever O,'and so ondurin'g the operation of themachine.

D is the driver-bar, which is raised upward kind.

d is the driver, secured to the lower end of the driver-bar, as usual.

E is a reel containing the continuous nailwire F, which isintermittently fed downward by means of the feed-rollers G G, in theusual manner.

H is the nail-carrier shaft, located in a bearing in the head of themachine and caused to oscillate in said bearing by suitable automaticmechanism during the operation of shaping the nail. The mechanism foroscillating said shaft H may be connected directly or indirectly to thedriver-shaft, as may be most practical and convenient, and I wish tostate that I do not confine myself to any particular mechanism forimparting an oscillating motion to said shaft II, it being sufficientfor this purpose to state that an intermittent oscillating movement isimparted to said shaft during the operation of the machine.

In the drawings I have shown for this purpose a lever I, secured to therear end of the shaft H and adjustably connected to the lower end of alever 2', pivoted at 1 and provided with a pin or pin and roll i,actuated by a cam-groove in the cam I, attached to the shaft (4, asshown in Figs. 1 and 2.

The nail-carrier shaft H is provided with a transverse perforation h,adapted to receive the nail-wire F, from which the nail fis out OKprevious to being driven into the sole or heel of the boot or shoe. Theupper surface of the nail-carrier shaft H is provided with alongitudinal dovetailed recess in which is inserted the perforatednail-head-forming die II, having a recess or countersunk portion h atone side thereof for the formation of the head f of the nail, asrepresented in Fig. 20. The perforation h in the rock-shaft H and die His sufficiently large to enable the headed nail to be driven freelythrough such perforation, as shown in Fig. 20.

Surrounding the nail-carrier shaft H are two annular disks K L, theformer being the stationary rear one and the latter being theoscillating front one. The stationary disk K is preferably made concaveto fit againstthe convex inner side of the movable disk -L, as shown.

M is a perforated cap secured to the front of the machine, and in saidcap the movable disk L is journaled.

The disk L is held in close contact with the disk K by means of anadjustable nut m, screwed through the cap M, and a washer m, interposedbetween said nut and the disk L, as shown in Fig. 3.

To the disk L is secured a lever N, to which a rocking motion isimparted from a lever O, secured to a rook-shaft O, journaled inbearings in the head of the machine, said rockshaft 0 being actuated byany suitable mechanism from the driving-shaft of the machine.

To the shaft 0 is attached a lever X, provided at its upper end with apin or pin and roll X, engaging in a side groove on the rotary cam-diskY, secured to the driving-shaft a, as shown in Fig. 22, and by thisarrangement a rocking motion is imparted to the shaft 0 and its lever 0.Any suitable or wellknown mechanism may be used for such purpose withoutdeparting from the essence of my invention.

In practice I prefer to arrange between guides 'n 'n on the lever N asliding block it, having a pin 91., adapted to be received in a recessor perforation O on the lever 0, although any other suitable connectingmechanism between said levers N and 0 may be used as may be mostpractical.

The rear stationary disk K has at its upper portion a semicircularrecess 70, through which the driver (Z passes during the nail-drivingoperation. To the right of such groove is a wire-receiving groove theright-hand portion of which forms an inclined cutting edge 70', (shownin Figs. 11 and 12,) which in connection with a similar cutting edge onthe movable disk L serves to cut the wire F at an angle, so as toproduce the pointed end f on the wire nail, as shown in Figs. 20 and 21.

k in Figs. 11 and 12 is a clearance-space for the chips f Fig. 21, whichare cut off from the wire F during the pointing of the nails.

At the lower portion of the disk K is a clearance-space k for allowingfree passage for the driver cZ during the nail-driving operation.

The movable cutter L has at its upper portion a wire-receiving space Z,to the right of which is an inclined cutting edge Z, as shown in Figs.13 and 14:, corresponding to the cutting edge 70 on the stationarycutter K, and the said cutting edge Z, in connection with the cuttingedge 71)", serves to out OK the wire in the inclined pointed mannerdescribed during the rocking motion of the disk L. In front of thecutting edge Z on the disk L is a ledge or rest Z", (shown in Figs. 13and 14,) on which the wire is supported during the cutting operation.

Z in the upper portion of the movable disk L is a clearance-space forthe driver d, and Z is a similar clearance-space for the driver in thelower portion of said disk L to permit the driver to move freely up anddown during the nail-driving operation.

P is the centrally-perforated nipple or nail driver tube, secured to thelower portion of the head of the machine directly in alinement with thedriver, as is common in devices of this kind.

The one-sided head f on the nail f is formed While the nail-carriershaft His being moved toward the position shown in Fig. 6, causing aportion of the upper end of the severed nail to be turned over to oneside into the recess h in the block H by the conjoint action of the saidshaft II and the cutting-disks K and L.

The operation of the machine is as follows: The operator places the shoeor material to be nailed against the shield O on the lever C and pressesit upward until the work is brought against the under side of the nippleP, by which the loose friction-pulley B is caused to convey a rotarymotion to the driving-shaft, as is common in starting mechanism of thiskind. During the first'portion of the rotation of the driver-shaft thedriver-bar is raised against the influence of its spring sufficiently toraise the driver entirely clear of the disks K L, as shown in Fig. 4,and at the same time the nail-carrier shaft H is rocked to the positionshown in Fig. 4 for receiving in its perforation h the Wire F, which isfed into it the proper distance by the action of the feed-rolls G G. Themovable cutter L is then rocked sufficiently to shear off and point thewire and at or about the same time to form the head of the nail byforcing a portion of the upper end of the severed nail into depression hin the die or block I-I, attached to the upper side of the nail-carriershaft H, as shown in Fig. 5. Thenail-carrier shaft is then rocked, sothat its hole his carried toward the left beyond the driver, as shown inFig. 6, and is then turned in an opposite direction to relieve the headof the nail from the recess h in said shaft and so as to bring the holeh in alinement with the driver, as represented in Fig. 7, when thedriver is automatically released and forced downward by the influence ofits spring, causing the now pointed and headed wire nail to be driveninto the work, after which the nail-carrier shaft and movablecutter-disk resume their original positions, and so on during theoperation of the machine.

Having thus fully described the nature, construction, and operation ofmy invention, I wish to secure by Letters Patent and claim' 1. In anailing-machine, the combination with a reciprocating driver-bar anddriver, of a wire-feeding device, a perforated rocking nail-carriershaft, a stationary cutting-disk,
